    摘要: The invention relates to a hydraulic press (10) and a method for operating a hydraulic press (10) in cycles. The aim of the invention is to lower energy consumption in a method for shaping workpieces by means of a hydraulic press and in a hydraulic press for shaping workpieces. With respect to the method, said aim is achieved in that each cycle has at least one phase in which the storage pressure p
    s in the accumulator (15) causes hydraulic fluid to be pressed from a hydraulic accumulator (15) into a chamber (11.1, 11.2) of a hydraulic cylinder (11) of the press (10) in order to move a ram (12) of the press (10) relative to the cylinder (11), said ram, to which a tool (21) for shaping a workpiece can be coupled, being coupled to the cylinder (11); and in that in at least one portion of each cycle, a hydraulic pump (13) driven by a motor (14) delivers hydraulic fluid to the accumulator (15) at a charging volume flow rate, and the storage pressure p
    s is adjusted to a reference value P
    SOLL by setting the speed of the motor (14) to a nominal motor speed n
    N and to at least one intermediate value n
    z , where 0 z N . .

    摘要: The invention relates to a method and a device for producing a three-dimensional perform during the production of fiber-reinforced molded parts. The method is carried out using a device (1) which comprises at least one draping device (2) for a fiber fabric staple (3) and a shell mold (5) for forming the preform (6) from the fiber fabric staple (3) by means of the draping device (2). The method is characterized by carrying out the following steps: a fiber fabric staple (3) is placed or formed between the draping device (2) and the shell mold (5); at least one draping tool (8) is then deployed from the draping device (2), thereby at least partly introducing the fiber fabric staple (3) into the shell mold (5) until the fiber fabric staple (3) is pressed against the shell mold (5) by means of the draping tool (8) and immobilized there; and then additional draping tools (8) are deployed in a predetermined order either individually or conjointly from the draping device (2) towards the shell mold (5), the order resulting from the flow properties of the fiber fabric staple (3).

    摘要: The invention relates to a method for constructing and consolidating a laminate (90) and to an associated tape-laying device (1). The inventive step for the method consists in carrying out the following steps: a) feeding a tape (93) to be laid, which is provided with binder substances and/or matrix substances, to a laying device (20); b) laying up tape (93) by means of the laying device (20); wherein adjacently-laid tape (93) defines a tape layer (92) of a tape structure (91); and c) controlling the obtaining of a consolidated laminate (90) by: advancing tape (93) laid on the uppermost tape layer (92) of an already-laid tape structure (91) towards an ultrasonic excitation system (30), or vice versa; successive plasticization in the adjoining joining zones (95) of the tape (93) advanced towards the ultrasonic excitation system (30) and of the uppermost tape layer (92) carrying said tape (93) of an already-laid tape structure (91); successive bringing together of the plasticized binder and/or matrix substances in the adjoining joining zones (95) of the tape (93) advanced towards the ultrasonic excitation system (30) and of the uppermost tape layer (92) carrying said tape (93) of an already-laid tape structure (91); wherein in at least one sequence of the method (whilst tape (93) to be laid is laid by means of the laying device (20) on the uppermost tape layer (92) of an already-laid tape structure (91)), adjacent tape (93) that has been previously laid is simultaneously consolidated.
